ATTACHMENT FOR WATER-CLOSETS.

SIE ECIFIGATION forming part of Letters Patent No. 601,375, dated March 29, 1898.

Applicationfiled March 13, 1897.

T0 (bZZ whom it may concern.-

Be it known that I, JOHN A. FREY, residing at Ottumwa, in the county of \Vapello and State of Iowa, have invented a new and use ful Attachment for lVater-Closets, of which the following is a specification.

This invention relates to certain improvements in water-closet attachments, and more particularly to an improved chain operating mechanism for automatically opening and closing the valve of a flush-tank, so that there will be a ready inflow of water to the bowl.

The object of my invention is to providea water-closet attachment and to provide certain mechanism attached to the chain depending therefrom, so as to enable the party using the seat to flush the bowl without the necessity of pulling the chain.

A further object of myinvention is to provide a chain operating mechanism for flushtanks automatic in action, the parts being so arranged that the water will onlybe allowed to flow into the bowl after the party sitting thereon has arisen.

With these and other objects in View my invention consists in certain novel features of construction and in combinations and arrangements of parts more fully described hereinafter and particularly pointed out in the claims.

Referring to the accompanying drawings, illustrating my device, Figure l is a perspective view of the device in operative position. Fig. 2 is a vertical section of my improved mechanism, and Fig. 3 is a detail sectional view of the screw or cap to regulate the height of the rod within the casing.

In carrying out my invention I have shown an ordinary flush-tank A, having the depend ing chain B and a closet C, the same having the usual bowl D and hinged seat E, the seat being supported upon suitable legs F.

G indicates a suitable base fastened to the floor or other support and being provided with the outer arm H, having the upwardlycurved portion and a hook I, near the upper part thereof.

J' represents a hollow tube secured to the base G and being provided with shoulders K, having the central openings extending therethrough.

L indicates a rod passing through the cen- Serial No. 627,320. (No model.)

tral portion of the tube, the same being provided with a coiled spring M, surrounding the same, the lower edge thereof bearing against the upper face of the shoulder K, while the uppermost coil bears against the top shoulder N, so that the spring can be held against the faces of said shoulders. The upper portion of. the tube or casing is open, a screwthreaded cap 0, having a central opening P, through which the rod passes, being employed to close the same. Q represents the upper extended end of this rod, the same being constructed in such a manner that the length of said rod can be regulated.

The rod Latits lower end is screw-threaded to receive a connecting bar or link R, and S represents an upwardly-extending bar pivoted to one end thereof and havingthe grad ually upward tapering rod T. This rod is provided near its upper portion with the notched part U, so that the inclined portion W is formed above the same to bear against the inner edges of the hooked part of the armH, the extreme end of said arm preferably extending and being secured by the cap between said cap and the outer Wall of the tube.

To the rear of the taperingrod T is secured a fiat spring Y, the shortly described.

Z indicates a lever fulcrumed to the arm H, asshownat A, one of its ends being connected to the chain operating the valves of the tank. Its opposite end has an extended portion A the function of which will be hereinafter set forth. Directlyin the rear of this extended end is a vertical rod B, carrying a piston O, the same being adapted to move back and forth within a compressed-air chamber D.

The operation of the device is as follows: Supposing the parts to be in the position shown in Fig. 1, should any pressure be brought to bear upon the seat the rod D will be forced down by means of the coiled spring and at the same time the tapering rod T will also be forced'in a downward direction. As the notched part of this rod reaches a point below the extended end A of the lever carrying the chain said extended end will be forced into said notch, the spring Y tending to hold the same in place. As the pressure upon the seat is released the tapering rod T will gradpurpose of which will be ually raise the lever C, by reason of the coilspring, until it reaches a point directlybelow the hooked part of the arm I-I,When it will be thrown off, thereby pulling-the chain and allowing the water to escape from the tank.

By means of the compressed-air chamber carrying the piston-rod secured to the lever Z at one end the rapid movement of said 1ever is retarded on its return, so that the water will be allowed sufficient time to flow to the bowl before the lever reaches its normal position.

The invention is very simple in construction and composed of but a few parts, and by its use I am enabled to flush the bowl of a closet after using the same without the necessity of reaching for the chain that is usually employed for opening the valves of the tank in order to allowthe water to flow to the bowl.

Various slight changes might be made in the forms, constructions, and arrangements of the parts described without departing from the spirit and scope of my invention. Hence I do not wish to limit myself to the exact construction described, but consider myself entitled to all such changes as might fall within the spirit and scope of my invention.

Having thus fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A flush-tank-operating mechanism consisting of a base secured to the floor beneath the seat, a tube mounted thereon, a rod in said tube, a spring to normally hold it in its upper position against the under side of the seat, an arm projecting horizontally from said rod through a slot in the tube, and a vertical bar connected to said'arm, and the lever engaging the bar and connected to the chain which hangs from the tank to draw the chain downward when pressure on the seat is removed, substantially as described.

'2. A flush-tank-operating mechanism consisting of a base having the curved arm and carrying a tube provided with a spring-actuated rod, the upper end thereof extending through the top of the tube, a bar on the lower end of the rod, a tapering rod pivoted thereto, an operating-lever pivoted to the curved arm having one of its ends extended and its opposite ends attached to the chain of the tank, and means for operating the same substantially as described.

3. A flush-tank-operating mechanism comprising a base secured to the floor, a vertical tube mounted thereon, and a curved arm con necting the upper portion of the tube with the base, and provided with an inclined plane in its upper end, in combination with a vertical spring-actuated rod in said tube upon which the seat rests, an arm projecting therefrom through a slot in the tube, a lever projecting vertically from said arm and having a curved upper end to engagesaid inclined plane, and a lever pivoted to thecurved arm whose outer end is attached to the tank-chain, and whose inner end engages said vertical lever in the manner substantially set forth. 7

4. A flush-tank-operating mechanism comprising a base secured to the floor having the curved arm and tube mounted thereon, in combination with a spring-actuated rod in said tube engaging under the seat, a horizon tal arm projecting from the lower end of said rod, a vertical lever pivoted to said arm, a lever pivoted to the curved arm attached to the tank-chain at one end and engaging the vertical lever at the other, an air-chamber on the base, and a piston-rod attached to a pistion in said air-chamber, and at its outer end attached to the inner end of said pivoted lever, substantially as described.
